We'll Tell You How to Fix That...
Some email systems separate your emails according to whether they think their PRIMARY, SPAM, PROMOTIONS, or SOCIAL MEDIA generated emails. To prevent this training course and all its emails being redirected and lost in your account:
1) Find your promotions tab or section of your account (as shown in the image above);
2) When you locate the promotions section, add a check mark to the left of our email, to select it;
3) Uncheck the Label Promotion or relabel the email as a General/Primary email (as shown in the image below).
